The present invention relates `to scuttle ports and like tight closed windows, and particularly toa tight closing device therefor, and is an improvement in or modification of the invention forming the subject matter of my prior patent application No. 322,369 of tion. f.

The elimination of `the packed joints renders it possible to produce a tight closing device, the Vconstruction and 'operation of which are simpler than is the case inthe apparatus previously described.

Y Some preferred constructional forms according tothe invention are illustrated by wayY of example inthe accompanying drawings, in' which Fig. 1 is a sectional elevation of the lower part of a scuttle port closing from outside inwardly against rubber packed joints toc closedV position.

@ether Vwith its operating members, in the Fig. 2 is'likewise a sectional' elevation of open position,

i the lower partof the same scuttle port in the Fig; 3 is a sectionalielevation of the device employed for rendering aA scuttle -port tight closing' without'using any y rubber or other packed joint.

4 is a sectional elevation4 offthelower part of a scuttleport in the position of tight closure obtained by the application device shown in Fig. 3 and Y of the Fig. 5 shows a modification of the scuttle port shown in Fig. 3 in the openv position.

Fig. 6 shows a further embodiment in section. i.

The tight closing and the opening of the scuttle port shown in Figs. 1 and 2 is eected simply by the manipulation of a toothed wheel or pinion llwhich is in permanent engagementtwith teeth 10 provided on. a cylindrical crown or ring 6 having a screw thread 5 engaging with a corresponding screw thread 34 cut in the movable ring 35 carrying the pane holder 8 of the scuttle port, which lcan be adjusted by turning freely on pivots 36 located diametrically opposite to onefanother, one `only of said ,pivots being shownin the drawings.

.The movable ring 35 is hollowed out on one of its peripheral surfaces so as to form a groove vfor the reception of a rubber joint 37 which ensures the tightness of the closure at the exterior, whilst a counter ring 38 is fixed on the framework of the scuttle port. This last named ring is also grooved for the recep-V tion of ajoint 39 which ensures the tightness of the closure at the interior. f f

A cover 40 having a tighteningjoint is fixed by knownmeansto the pane holder. The said lcover is adapted to allow the scuttle port tobeopened withoutthe necessity for its removal. By :turning the pane holder 8 shown in Fig. l,-18OD round its pivots 36,7the cover il() may protect the scuttlev port on its sea side againstrough seas.

The exterior surface of the pane Aholder8 is curved in accordance with the jradius of curvature of the scuttle port inV such manner as to ensure that by contacting with the surface of the ring 35 having the same curvature a tight closure of this movable part will be obtained. j ,j

The actuation of this device is effected by the-rotation of the toothed wheel 11, which operates the ring 6, so that the latter through the medium of its Screw thread 5 displacesthe movable ring which carries with it in its movement the pane holder 8 of the scuttle port.

In this device the screw threads 34 are not cut as in the devices previously described.

The scuttle port will be opened or closed according to the direction of rotation of the wheel ll.

In the scuttle port device shown in Figs. 4 and 5 the rubber tightening joints have been entirely eliminated, a tight closure being obtained by direct contact of the pane holder with the corresponding surfaces.

The device employed in order to obtain this result is shown in Fig. 3.

The pane holder 8 (Figs. 3, 4 and 5) is provided on each one of its faces with grooves in such manner as to produce raised portions 4l of conical section similar to the section of a truncated conical screw thread. One of these conical portions enters a groove 42 of corresponding cross section eut in the framework 2 of the scuttle port, and the other one of the said portions enters into a groove 43 of the same cross section cut in the movable ring 44, the said ring having screw thread 45 engaging with a screw thread 5 cut in the ring 6, which is rotated by means of the teeth l() permanently in engagement with the operating toothed wheel l1.

In order to allow of the movements necessary for effecting the opening and the closing of the scuttle port the pane holder 8 is arranged concentrically in the interior of a ring 46 into which it enters and with which it contacts with slight friction. rIhe said ring 46 is carried on a circular support 4T rigid with the framework 2. rihe said support is transversely grooved so as to form a guide 4S into which a tenon member 49 passes, and serving at the same time as a guide for the ring 46.

lVhen the scuttle port is in the closed position as shown in Fig. 4, it is only necessary in order to open it, to operate the one wheel l1. The said wheel on its rotation actuates the ring 6 through the medium of the teeth l0, whilst the said ring 6 through the medium of the screw thread 5 displaces the groove 43 cut on the ring 44, thus causing it to move out of contact with the pane holder 8. Ifvthe manipulation of the toothed wheel. 1l is continued, the ring 44 likewise continues its movement in advance of the scuttle port which has the effect of bringing the stop 50 carried by the said ring into contact with the tenon member 49 rigid with the ring 46 carrying the pane holder 8. As soon as this occurs, the backward movement of the ring 44 causes a. similar movement of the pane holder 8 thus allowing of the adjustment of the scuttle port by turning it about the pivot 36 rigid with the supporting ring 46. The position of maximum opening is indicated in dotted lines in Fig. 5.

The fixing of the scuttle port in the desired open position may be effected in various ways, of which only two are indicated in the drawings. One method of effecting this (see Fig. 4) consists in tightening up the screw 5l against the pivot 36. The other method of effecting the desired result (see Fig. 5) consists in the manipulation of a right and left handed screw 52 acting on a sector 53 fixed on one of the pivots 36.

As in the case of the preceding device, it is easy to fit on this scuttle port a cover similar to that shown in Fig. 1.

The device described in which all packed joints are eliminated may be applied to all the constructional forms illustrated and described in my aforesaid prior application No. 322,369 of 1928.

The employment of: the device according to the present invention, presents numerous advantages, of which the principal ones are:

Great simplification in the construction and operation of the scuttle ports, and the assurance of absolut-ely tight closure of the latter obtained by a simple and rapid rotation of the parts in contact, one of which may, if desired, be made of a metal having a different resistance from that of the other part on which the first named part bears.

The devices according to the invention can be applied to scuttle ports of all dimensions and to all similar classes of openings. It is to be understood that lthe constructional form according to the invention can be modified in a variety of ways.

`In 6 the scuttle port is a slight modification ofthe scuttle ports shown in Figs. 4 and 5 with the difference that this modified embodiment enables one to put a protecting cover 40 on the inside of the scuttle port, a tightening joint 55 being provided for obtaining a tight closure between an edge of the pane holder 8 and said cover 40, whilst a flange 56 is provided along the whole circumference ofthe cover 40, on which flange 56 a known means acts upon for fixing the cover onto the pane holder. This known means consists in a screw threaded ring 54 of Z-shaped cross section, to be screwed by hand onto the cover 40, thus pressing the joint 55 tight onto the edge 60 of the pane holder. A collar with inward .projecting flange 58 serves as a guide for the screw threaded ring 54 during screwing and fastening of the cover or shutter 40.

By turning this pane holder 8 together with its shutter or cover 40 around its pivots 36 for 180 degrees i. e. half a turn, the same cover or shutter 40 comes to lie on the outside of the scuttle port thus protecting the latter on its sea side against rough seas and Waves.
